Abstract
The invention relates to the field of alloys. For a long time, the punch of the die casting machine is made of cast iron, so that the wear resistance, the heat conductivity and the toughness of the punch are poor, and the service life of the punch is short. The punch manufactured by the invention has good wear resistance with various pressure chambers after trial for one year, greatly improves the service life and the working reliability, and can be continuously replaced for one and a half months without replacement. Obviously improves the production efficiency and reduces the production cost, and the alloy consists of beryllium , nickel (Ni) and copper (Cu).
Description
The invention belongs to copper base alloy field (C22C)
For a long time, the pressure die-casting machine drift generally adopts cast iron quality to make.By retrieval, finding no alloy makes.Because this drift adopts cast iron quality, therefore, performances such as wear resistance, thermal conductivity and toughness are difficult to adapt to diecasting punching head high speed, worst hot case condition, its life-span is extremely short, under conventional working condition, the inferior need of pressure die-casting machine per tour changed drift about 3 times, influenced the continuity that pressure die-casting machine is produced, and greatly reduces pressure die-casting machine production efficiency.
The objective of the invention is to adopt the beryllium copper material to substitute cast iron quality for the life-span that prolongs the pressure die-casting machine drift.
Content of the present invention is: adopting with beryllium (Be), copper (Cu) is the Be-Cu-Ni beryllium copper material making diecasting punching head of base.Its concrete composition and content are such:
Be:0.8～2.5% (weight)
Ni:0.5～2.0% (weight)
Cu:96～98% (weight)
The preparation method: beryllium copper is melting in medium-frequency induction furnace or pit type coke-fired furnace by weight proportion, (heat treatment parameter is: 800 ℃～830 ℃ of Heating temperatures through the quenching modifier treatment more then to adopt permanent mold casting → strand, be incubated 1～3 hour) → oil quenching → tempering (280 ℃～330 ℃ of temperature are incubated 1.5～4 hours) air cooling.
Embodiment: by following component and weight melting in medium-frequency induction furnace or pit type coke-fired furnace.
Be:1.85% (weight)
Ni:1.42% (weight)
Cu:96.7% (weight)
After ageing treatment, the mechanical property of this alloy is: δ
6=125MPa δ=5%
HB=250 satisfies the job requirement of die casting head fully.
Good effect of the present invention is: have good physicochemical properties and resistance to corrosion 1.; 2. have Good heat conduction, electric conductivity and creep-resistant property; 3. have good mechanical performance and wearability. Change On probation through 1 year with the MS-1 type permanent seal cooling beryllium copper diecasting punching head that this alloy material is made, with all kinds of pressures chamber Running-in ability good, the working life of drift can reach the constant replacing of one and a half months continuous operation, prolongs significantly Life-span, greatly improved production efficiency, reduce production cost, and filled up domestic and international blank.
Claims (2)
1. the alloy of a diecasting punching head is characterized in that being made up of beryllium (Be), nickel (Ni) and copper (Cu).
2. alloy according to claim 1 is characterized in that:
Be:0.8～2.5% (weight)
Ni:0.5～2.0% (weight)
Cu:96～98% (weight)
